“…In passive control, various vibration suppression and sound insulation materials have been developed rapidly in recent years, and people have also designed various vibration isolators and sound absorbers. There are some limitations in traditional vibration reduction techniques [3], such as vibration insulation, dynamic vibration absorption and damping vibration absorption. The equipment must be larger for vibration insulation technology.…”

As a new kind of artificial material developed in recent decades, metamaterials exhibit novel performance and the promising application potentials in the field of practical engineering compared with the natural materials. Acoustic metamaterials and phononic crystals have some extraordinary physical properties, effective negative parameters, band gaps, negative refraction, etc., extending the acoustic properties of existing materials. The special physical properties have attracted the attention of researchers, and great progress has been made in engineering applications. This article summarizes the research on acoustic metamaterials and phononic crystals in recent decades, briefly introduces some representative studies, including equivalent acoustic parameters and extraordinary characteristics of metamaterials, explains acoustic metamaterial design methods, and summarizes the technical bottlenecks and application prospects.

“…The control of unwanted vibrations and noise can be performed with passive control PZT shunt circuit [26]. This control deals with a direct piezoelectric effect that modifies the structure's rigidity and damping properties with the addition of circuits with different combinations of resistive, inductive, capacitive elements, and switches [11]. The piezoelectric materials allow the emergence of said intelligent materials, because when changes occur in the state variables in a mechanical, physical domain [20].…”

“…PZT shunts to promote vibrational control can be simulated via the finite element method (FEM), which requires a large number of elements in the mesh [3,11]. An alternative to FEM in dynamic simulation and analysis is the spectral element method (SEM).…”

The study analyzes the dynamic behaviour and vibration attenuation of an Euler Bernoulli beam coupled with a piezoelectric layer. The vibration attenuation is given by the shunt circuit connected to the piezoelectric. This paper shows different shunt circuit impedances and how they affect the system's frequency response (FRF) functions. The spectral element method is used to model the intelligent material under analysis and has its function based on the exact solution of the wave equation, therefore, a single element is necessary to model the structure. The estimated responses for each shunt configuration express a relationship with the passive components used in the respective circuits. In each case, the circuit has a particular effect on FRFs.

“…A recent paper by Ikegame et al [4] gathers tuning formulas for usual configurations and objectives at hand. Gripp and Rade [5] reviewed a number of works and applications of piezoelectric shunt damping. Interestingly, absorbers relying on the resonance of an added device also come in various forms and are used in a variety of domains.…”

This study presents the practical realization of a digital vibration absorber that, owing to the flexibility provided by the digital unit, synthesizes linear and nonlinear shunt circuits. The absorber, composed of a microprocessor and a current source, is connected to the host structure with piezoelectric patches. The performance of both circuits is compared experimentally for a nonlinear host structure. The superiority of a properly-tuned nonlinear absorber over its linear counterpart is validated, but the limits of the nonlinear absorber are also explored. Moreover, the accuracy of the tuning procedure and formulas is assessed through experimental parametric studies.
